Description

TVH1 dvb-c source EPG work perfect all channels EPG is OK.
TVH2 take streams from TVH1 via IPTV Automatic Network,
but channels don't have EPG on TVH2 ... Actually have EPG,
but it come, long time after EPG scan finish.

Same can be seen in VLC log EPG come 5+ second after channel start.
If same streams are streamed from MuMuDVB in place of TVH1,
"epg scan" take EPG on a moment.

Interconnect between TVH will solve this /already have request for this/
Or just EPG internal reader from URL. /will make such feature request if needed/

Updated by saen acro over 6 years ago

On TVH2 I have DVB-S tunners
problematic are DVB-C from IPTV

#4

Updated by Jaroslav Kysela over 6 years ago

I need to inspect traces - the standard logging does not show much for eit tables.

#5

Updated by saen acro over 6 years ago

Sorry but Wiki image is outdated (!)

new log uploaded

#6

Updated by Jaroslav Kysela over 6 years ago

There are EIT events in the log. Unfortunately, I cannot tell you what's wrong, because I don't know what you expect.

#7

Updated by Jaroslav Kysela over 6 years ago

I suggest to configure only one test mux in the automatic network and analyze the behaviour of TVH2.

#8

Updated by saen acro over 6 years ago

Im try to play via VLC from TVH2 and then from TVH1 same channel
both use PASS profile /with overwriting is impossible to be edited/
attaching log
no time stamps in vlc logs

just like pid=18 from iptv is cut or not used

#9

Updated by saen acro over 6 years ago

One more detail
TVH1 send in stream only NOW/NEXT event EPG

#10

Updated by Jaroslav Kysela over 6 years ago

Looking more to this: It seems that the EIT events are in EIT table 0x60 (other TS). Those events are FILTERED when you enable EIT rewrite (or SID rewrite which will implicitly enable all rewrites):

static void
pass_muxer_eit_cb(mpegts_psi_table_t *mt, const uint8_t *buf, int len)
{

....

  /* filter out the other transponders */
  if ((buf[0] < 0x50 && buf[0] != 0x4e) || buf[0] > 0x5f || len < 14)
    return;

Zero Effect, same as before :(

#13

Updated by Jaroslav Kysela over 6 years ago

The traces shows the imported events nicely, so you can investigate this more yourself. The key is if EIT events are broadcasted in the mux where the service is broadcasted.

60sec curl download from both
command used

curl -m 60 --output tvh2.ts http://localhost:9981/stream/channelid/1826398699

Same channel but size is totally different ???

DVB-C >>> TVH1  >>>  TVH2  >>> Clients
               16Mb       21Mb (60sec)

#16

Updated by saen acro over 6 years ago

I'm start to be confused?
http://www.digitalekabeltelevisie.nl/dvb_inspector/ nice program work in windows and linux just need JAVA

record from TVH1

there is 0x4E (78) and 0x50 (80) events

but after stream go to TVH2

on output there is no EPG also no EPG inside

Astra send only 0x4E

and MuMuDVB send both 0x4E and 0x50

You must upgrade all tvh instances also wait at least 40 seconds - the new EPG detection mechanism usually waits for first 20 seconds to detect the right EIT grabber.

50% success now/next events is OK (0x4E (78)),

I'm guessing but, on first TVH I filter Audio subtitle streams, leaving local language only.
Is it possible this to brake EIT.

#25

Updated by Jaroslav Kysela about 6 years ago

Try again code from comment # 11 (I fixed the wrong tsid/onid in EIT events recently and the current code filters out the EIT events for other transponders - your broadcaster might mark the events wrongly).

Modify pass_muxer_eit_cb() function not pass_muxer_nit_cb() with the code from comment # 11. Also, wait for few minutes to get EPG data - the complete data are broadcasted in chunks.

first TVH with take from DVB-C get EPG for week in less then 2 seconds per mux
on second TVH EPG scan give up after first stream

I doubt. The speed must be identical.

I tried to fix that in v4.3-1461-g7e0cda035 (inserting zero events to keep the SI tables consistent).

I mean to test the original reported issue (epggrab tooks too long). As I already wrote, the other VLC messages (except the CRC32 error) are problem of VLC, not TVH.

The EIT grabber is a bit delayed in the recent tvh versions to detect the various extensions (Freeview, Freesat etc.). It might be possible to do this detection only once and save it to the mux configuration.

#48

Updated by saen acro almost 6 years ago

The only used grabber is EIT: DVB Grabber
Why TVH store EIT and pass it after 1min after stream start?

#49

Updated by Jaroslav Kysela almost 6 years ago

TVH does not store EIT contents at all, but it will gather SDT/NIT info before it decides which EIT grabber will be activated, thus the delay. You should get first EIT in ~30 seconds.

#50

Updated by Pablo R. almost 6 years ago

I imagine that 2 tvh would mean double the time, because until the first one provides the data, 30 seconds will pass, and the second another 30... (60s)

#51

Updated by Pablo R. almost 6 years ago

But I think that if there is only one activated grabber tvh should not wait anything, right? the action is obvious.

I reimplemented the OTA EPG grabber selection in the latest 4.3 - the detection is run only once, then the detected module is stored to the mux, so you should see the data immediately on the output after the first epggrab.

No way. The translations are updated only for the stable code (4.2 at the moment).
